WHEEL-PLOW.

SPECIFICATION forming part-of Letters Patent No. 230,528, dated July 27, 1880.

i Application mcd Apm'ies, issn. (No model.)

To all whom it may concern Be it known that l, ROSWELL M. CLARK, of McPherson city and county, State of Kansas, have invented an Improvement in Wheel- Plows, of which the following is a specification.

This invention relates to wheel-plows for heavy work; and it consists in a novel combination of parts to facilitate turning, a simple and efficient combination for raising and lowering the plow from the front end of its beam, so as to utilize the leverage thus afforded, and a combination of parts for suspending the plow within the frame in such a way that the plow is not drawn by the beam, but is propelled from behind, so that the front end of the beam can be raised and lowered, as aforesaid, independently of the draft.

Figure l in the accompanying drawings is a side view of a plow illustrating this invention. Fig. 2 is a top view of the same, showing by full and dotted lines different positions of certain parts. Fig. 3 is a view of the plow proper, showing its braces. Fig. 4 is a front elevation.

Like letters of reference indicate corresponding parts in the several gures.

A represents a continuous frame, preferablyT of bar-iron, its widest end in front, and proportioned to the width between two furrows of a given size, and its landside straight.

B B2 represent two wheels, which support the frame A and its load, and O represents a mold-board plow, which may be of any approved pattern. The latter is suspended within the frame A, ne'ar the landside thereof, as hereinafter more particularly described, and the wheel B is arranged immediately behind it, so as to run in its furrow. The wheel Bibeinglocated at the ri ght-hand forward extremity of the frame, and to one side of the line of the wheel B, may run in a parallel furrow ahead ofthe plow. The axle a of the wheel B is mounted between parallel bars of the frame, and may be fixed as shown, or rotary.

rlhe axle a2 is a stud-axle pivoted to swing in a horizontal plane, as shown in Fig. 2. It consequently permits the wheel B2 to swing horizontally, as illustrated in Fig. 2.

To accommodate the wheel B2 in the position indicated by dotted lines, Fig. 2, the side bar of the frame is raised or arched, as shown in Fig. 1. To swing said wheel automatically which is connected by a rod, c2, to a clevis, C2,

pivoted to the frame.

D represents the drivers seat, supported above the wheel B; D2, the foot-rest.

The plow C is provided with a curved arm, c, the front end of which extends loosely into a sleeve, E, carried by the crank of a rock-bar, F, this' rock bar being mounted upon the frame A, and provided at one end with a short arm, e, from which a rod, f, extends to a handl lever, G, near the drivers seat. This handlever is pivoted near the lower end to the frame, as shown in Fig. l, and a concentric' notched sector, H, is attached to the same side bar of 'the frame, the notches receiving a bolt carried by the lever G, so that the latter may be held in dierent positions. By this combination of devices the driver' can readily raise and lower the plow from the seat D, utilizing in the former operation the leverage afforded by the plow-beam.

For propelling the plow I rely on a bifurcated push-bar or double brace, I. (Shown clearly in Fig. 3.) The front endof this brace fits in projections t' j beneath the share and mold-board. The rear forks of the brace l are pivoted to the side bars of the frame near the axle a. The plow is thus thrust from behind, so as to leave the beam free for the aforesaid adjustment.

The pivotal connection of the plow to the front end of the brace I permits the plow to be rocked to facilitate its operations, and this adjustment is effected by means of a bar, J, Figs. 2 and 4, loosely attached to the beam c, and-notched to engage with the upper edge of a side bar of the frame.

The frame A may be of any material and any approved construction as regards details of shape.v Apivoted tongue may take the place of the clevis-bar G2, and other `like modifications may be made without departing from my invention. 4

In some cases it is desirable to provide some means of support when the plow is raised, although ordinarily this is not essential. In

such cases I use a side bracket, T, which may be adjustable, carrying a steadying wheel or roller, U, Fig. 4; but I do not here claim the arrangement of the said roller, as it may form the subject of separate application for Letters Patent.

I claim- 1. The combination, with the frame of the plow, of a wheel, B, behind the plow, having its axis in a stationary bearing, and a wheel, B2, turning on a short axis pivoted at one side of theframe, to permit said wheel to be brought at right angles to the frame at one side thereof, substantially as set forth.

2.y Thebifurcated push-rod or brace I, in combination with the frame A, plow O c, and thtJ adjusting device, substantially as described, for moving the plow-beam vertically, substantially as set forth.

3. The combination of the hand-lever G, rock-shaft F, sleeve E,aud connecting devices In testimony whereof I have signed my 35 name to this specification in the presence of two subscribing witnesses.
